Hot rolling is primarily used to create curls and volume in the hair. This technique involves using heated rollers that are applied to sections of hair to help shape and set a curl or wave. The heat helps the hair cuticles to expand and then reform into the desired curl pattern as they cool down.

When the heated rollers are wrapped in the hair, they not only add volume by lifting the roots but also create soft, bouncy curls that can enhance the overall style. This method is effective for achieving different levels of curl, depending on the size of the rollers used and the duration the hair is kept wrapped around them.

The other options, while related to hair, serve different purposes. For instance, hair straightening typically involves the use of flat irons rather than hot rollers. Adding shine is often achieved through hair serums or finishing sprays, which help smooth the hair cuticle. Maintaining hair color involves techniques and products specifically designed to preserve the vibrancy of dye-treated hair, with hot rolling having no direct effect on coloring.
